TOY SCROLL SAW Application filed April 7,

My invention relatesto new and useful improvements in toy scroll sawssuch as are adapted to be hand operated, and obviously adapted for lightsawing.

The object of the invention is to deslgn a simpleand practicalmechanical toy of this character which can be inexpensively'manwfactured and placed upon the market to sell in volume, in small sizes,for twenty-five cents or less. 7

A further object of the invention is to so design the machine that itsfour more-important parts may be inexpensively stamped up from sheetmetal and assembled wlth the wire saw frame and cast metal cam wheel ina manner which will avoid expensive drill- 7 ing, tapping and othermachine work, which have heretofore been necessary in the production ofa scroll saw of this general character.

With these and other objects in view, the invention resides and consistsin the construction and novel combination and arrangement of partshereinafter more fully described, illustrated in the accompanyingdrawing, and pointed out in the claims hereto appended, it beingunderstood that various changes in the form, proportion, size, andminordetails of construction within the scope of the claims :1; may beresorted to without departure from 'the spirit, or sacrificing any ofthe advantages of the invention. 7 7

Similar characters of reference denote like or corresponding partsthroughout the several figures of the accompanying drawing forming apart of this specification and upon which Fig. 1 shows a side elevationof my improved toy scroll saw complete;

Fig. 2 illustrates the opposite side view of the saw shown in Fig. 1;

Fig. 3 illustrates a front elevation of the saw Fig. 4 is a detailedvertical sectional View a through the cam wheel and the fixed spindlesupport for the same; and

Fig. 5 shows a detached top edge view of the saw-frame carriage, betterto illustrate one of the two guide slots therein.

Referring in detail to the characters of refthat is secured to thecolumn through a bush- 1932; -S eria1 No.- 603,730.

erence marked 'uponthe drawing,'lO represents the base of the machinewhich, as will be observed, isfadapted to be blanked and stamped up fromsheet metal, at Whichtime one or more elongated openings 11 may be L'Jformed in its central portion to receive-the lower end portion of thevertically disposed sheet metal pedestal 12 upon which the saw table 13mounted, saidmounting being preferably accomplishedin the same mannerasthe connection at the bottomend ofv the pedestal by means of providingone or more elongated slots in the table to receive pro jected' endportions of the column. This column is preferably provided with a rib 14upon each of itsvertical edgeportions.

fThe saw-carriage 15fis also formeol'of sheet 7 metal that is blankedup, see Figs 3jand 5, to? form a main body portion in which a trans- Pverse cam slot 16 is formed, and having upper and lowerinwardlyfdisposed,flanges l7 and 18, each of whichis provided witha'slot 19,, seeFig. 5, to receive the ribbed column 12heretofore'inentioned. From the foregoing, it will beseen thatthecarriage is free .to be, reciprocated vertically uponthe column andalong with it the saw frame 20which is se-fl cured to the upper flange17- by means of screws'21 passing through holes in the lowerv endportion of the saw" frame, and 'engaging tapped holes 22 in the upperflange. 3 j The saw proper, designated as 23,.hasits1 opposite endportions secured in the slotted Y I ends 24 and 25 of the saw frame andis positioned to freely operate in acentral hole 26 of the table. Thecarriage 15, its saw frame and saw, are reciprocated on the columnvertically by means of an operating wheel 27 that is mounted upon ashouldered screw stud 28 ing 29 and a nut 30, the latter being mountedupon areduced threaded end of the screw in a way to. secure the same tothe column.

The wheel is provided upon its inner side with an eccentric cam 31 thatis positionedto turn in the before mentioned cam slot 16 in a manner toraise and lower its saw frame and saw, once with each rotation of thewheel. The wheel is further provided with-an oper-; ating handle 32 bymeans of which it is freely rotated on the stud 28 in away to turn itscamwithin the slot and move the parts in a manner to move the saw up anddown through the hole in the table.

The base of the saw may be provided with 7 one or more screw holes 33 topermit it to be clampedito a table and Whereby anj operator'maymoreeasily perform sawing opera;- tions by rotating the wheel with one handand gulding the stock to be sawed, with re:
